Password-based KDF cost parameters honoured unbounded from untrusted input across the remaining PBE entry points
In Bouncy Castle for Java before 1.86, several password-based key derivation entry points ran the KDF with cost parameters taken from the untrusted input being processed, without bounding them, so a small input could dictate an arbitrary amount of work before…

MLS membership checks compare a uint32 leaf_index as signed, admitting an out-of-range sender
In Bouncy Castle for Java before 1.86, the MLS implementation (org.bouncycastle.mls) holds RFC 9420's uint32 leaf_index in a signed int, so a wire value with the top bit set decodes to a negative number. That is a legitimate encoding rather than malformed inp…
